How do you purge everything in SpiceWorks inventory over 1 month old? We have closed a branch and moved a router to a new location but there is an entire Class C Subnet of DHCP client that no longer exist and keep showing up in Inventory reports.

Go to your inventory, pick a machine, one you don't want, then click the cog icon to the top right of the inventory window), then delete, another window will appear, you need to select what you want to purge by name, you can choose all.

do NOT tick the box to not scan again and it will pick them up as new, you cant do it by time, subnet or range, only DNS name, if you want to purge all, tick all. You cant purge only old data, its all or nothing.
